Removing the Chassis Fan

The chassis fan is mounted at the rear of the chassis.
WARNING
Follow these instructions to remove and replace the chassis fan:
1. If the NetServer is operating, power down the NetServer.
2. Disconnect the power cord and any external cables connected to the NetServer. If necessary,
label each one to expedite re-assembly.
3. Remove the cover and turn in the NetServer feet (so that the NetServer will lie flat on its side).
4. Lay the NetServer on its side (components showing).
5. Unsnap the air duct and move it out of the way.
6. If necessary, remove any accessory boards from the system board allowing clear access to the
fan mounting snaps.
7. Remove the fan by snapping out the four mounting snaps, disconnect the power connector from
the system board and lift the fan out and away from the chassis.

Before removing the cover(s), always disconnect the power cords and unplug
telephone cables. Disconnect the power cords to avoid exposure to high energy
levels that may cause burns when parts are short-circuited by metal objects, such as
tools or jewelry. Disconnect telephone cables to avoid exposure to shock hazard
from telephone ringing voltages.
Note that the power switch does not turn off the standby power. Disconnect the
power cords to turn off standby power.
